invincible styling gel This gel’s hold is no joke! So put it down and slowly back away if you’re not up for the strongest gel hold ever! This non-sticky, no-flake formula is powered by a high-tech styling agent – we call it Alpha XTR. Call it what you want, it lets you take your hair to new heights. Or do your own thing and cement your individual style. And when the party comes to an end, easily un-glue with a little shampoo. Go ahead – style away!
